Some pics of the final buildout of my train depot. Cut from .060 styrene on my Probitix X90. Finished up with Rustoleum flat cammo colors from rattle cans. This should fare much better out in the elements than my wooden structures, plus styrene is way way easier to work with than wood.
I use Inkscape to draw the plans, then the free version of CamBam to make the G code cutting paths. The X90 uses a Dewalt dwp611 palm router driven by a super PID speed controller. All cuts are made with preciseBits 1/32 inch 2 flute endmills.
This is my newest critter design. A freelance sort of fantasy vehicle but it came out pretty good and was fun to build. A couple of 3D peoples and some resin cast details thrown in for good measure. Everything is cut out on the CNC machine except the fuel tank which is a piece of PVC pipe. (I cut those on the band saw). Anythow, I am planning on possibly selling these as kits or at least making the plans available, not sure how that’s going to work out quite yet…
Here is a shot of my Probotix X90 Desktop CNC machine. Works really GREAT, I love this thing.
One of my 3D printed 1/29 scale fellows on a CNC cut out Critter. Its a tiny locomotive I’ve designed based on a collage of prototypes from google searches. It’s cut out of sheet of 5mm finish ply and fits on a USA Trains 4 wheel power truck. I’ve left room for batteries and controls, I’m not a track power guy.
Two of my favorite 3D folks printed from Shapeways in 1:20 scale. At this size you get some great detail in the cheapest print medium. They are still pricey but what can you do? I’m working on molds for resin casts but they are an art form themselves. Raspberry Pi in the background, pencil in the foreground for size.
They are here:
So here ya have it, front, side and support of a building I’m working on. All the window and door openings look rough but will be filled with resin castings. There seems to be a sort of ‘black art’ to selecting the right bit for the right material and then getting the feedrate right as well. I’m closer to figuring it out I guess.
Super PID speed controller online and tested. Works GREAT! I built a custom enclosure out of styrene and did some surgery on the router to get the sensor positioned and the innards rewired. Way worth the effort.
I am almost ready to do some cutting, just need to get the vacuum system online and finalize my tool paths. Awesome.
Installing the Super PID into my router. Once I have this hooked up and running, I’ll be able to dial in any cutting speed within a couple of rpm. Sweet. That, coupled with the right bit should let me cut, carve and engrave wood, plastic and acrylic materials. Quite a learning curve here but it’s way fun.
Note: This page gets hit a lot and I’m sorry I don’t have more specific instructions on doing this mod but it’s all together now and works really well so I don’t want to take it apart to do a tutorial. I do remember this being rather easy, its basically as simple as bypassing the speed controller. I think I made one wire cut, drilled the hole and used one piece of shrink tubing. I followed the generic instructions on the Super PID page. Everything works very well, the LEDs still light up the work area and the PID lets you dial in the RPMs to within about 10 or so. It holds that RPM even chomping on some hard pine although I generally use mine to cut sheet styrene.
Another item: BE CAREFUL mounting the sensor, it must be VERY secure. Mine came loose after about 9 months or so and crept into the router. It didn’t hurt the router but it did grind the sensor down to a nub and destroyed it. Turns out it’s more or less easy to fix, a sensor can be had from Mouser.com electronics the part number is 512-QRE1113. However it will bring you to a complete stop as far as cutting out parts so beware. (2/22/2016) I’ll try to post up more pictures of my mods when I fix this.
Everything is now together, refurbished LinuxCNC PC, all the motors hooked up and working. Now I’m figuring out all the settings and things like accelerations and feed rates and all that. I can now see the benefits of limit switches, particularly as new as I am at this whole thing. But it’s coming together nicely, I’m quite pleased with it. It will be a while before I can actually try to cut something out but so far so good.
I wish I had a ‘before’ picture of this, you would not believe the disaster that was my shed!
Tons and tons of junk piled all over the place. Nasty. Nevertheless, after much physical activity and throwing away of ancient artifacts, here is my new floor and nice solid bench work. Talk about a strenuous weekend, I strained muscles I didn’t know I had. Ouch.
But it was worth it. I finally got started assembling my Probotix X90 3D Router.
Along the way I also lucked into a bunch of surplus windows boxes and flat screens so I promptly wiped em and installed Ubuntu. Sweet. They all have printer ports on them too, perfect for the X90 control box and Linux CNC. You can see one in the corner there.
I still have a ways to go, I’ve ordered a Super PID so I can dial in a router speed and cut plastic, in particular, styrene sheets.
A 3D printer at some point would also be nice but one thing at a time, eh? ha.
